CANE MILL.

T allam zomit may concern.

Be it known thatI JOHN P. GOLDEN, a citizen of the United States, and aresident of Columbus, in the county of Muscogee and State of Georgia,have invented certain new and useful Improvements in Cane Mills; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to whichit appertains to make shall be capable of use one at a timeso that if, one of said guide-knife portions shall have become worn theother (previously idle knife portions) can be .broughtinto active tionof the guide-knife structure. v i

A further object is to provide a guideknife structure for cane millswhich shall be substantial,providing wide bearing portions against thesmaller rollers,and capable of being easily and accurately adjusted topermit the cane to be fed in one or the other direction through themill.

A further object is to provide a guideknife structure for cane millswhich will operate to prevent the cane from getting past the flanges ofthe large roll to the gearing above or dropping to the bottom of themill.

A further object is to provide simple and efiicient means for adjustablysupporting a guide-knife structure in position relatively to the rollsto prevent possibility of the cane dropping between the smaller rollsand to insure the proper passage of the cane between the rolls.

With these and other objects in'view, the invention consists in certainnovel features of construction and combinations of parts Figure 2 is afragmentary front view, and

manner. relation to the rolls by reversing the posias hereinafter setforth and pointed out in Application filed November 16, 1922. Serial No.601,368.

Figure 3 is a similar view partly in section and partly in sideelevation.

In the drawings a portion of the frame ofa cane mill is represented at 1and has suitably mounted therein rolls 2, 3 and 4:, the r0112 beingconsiderably larger than the rolls 3' and 4: and is provided at. itsrespective ends with flanges 5, between which the rolls 3 and l projectso as to be cooperable with the peripheral face of the roll 2 in amanner to crush the cane represented at 6 as it passes, first betweenthe rolls 2 and 3 and then between the rolls'2 and 4:. I haverepresented the roll 3 as being disposed a short distance from theperipheral face of the roll 2 and between these rolls, the cane firstpasses but the roll 4 is shown in close proximity to the roll 2 so thatas the cane passes between said rolls .2 and 4 it will be completelycrushed, leavingnothing but the pulp or bagasse which will be dischargedfrom the mill in any approved My improved guide-knife structure isrepresented at 7 and is disposed between the rolls 3 and i -saidguide-knife structure being suspended by means of a rod 8 from thecasing. The rod 8 is threaded through one end of the structure? so as tobe adjustably connected therewith and the other end of said rod passesthrough an elongated slot 9 in the frame-work so that the structure 7may be adjusted relatively to the rolls and said rod is provided at itsfree upper ends with a head 10, betweenwhich and the framework a disk 11may be disposed. For 'the purpose of adjusting" the structure 7relatively to'the rolls and holding it at the desired adjustment to inisure close contact with the feeding roll, an adjusting rod 12 isemployed. This rod has a threaded portion 13 to pass through a threadedhole 14 in the structure 7 and the other end portion of said rod isthreaded as at 15 and passes through aslot or opening 16 in theframe-work and receives a thumb nut 17, between which latter and theframework a disk 18 may be disposed. The structure 7 is reversible intwo directions at right angles to each other as more particularlyhereinafter explained and said structure is therefore provided with twothreaded openings 14 for the accommodation'of the adjusting rod71 2 andit is likewise provided at its respective ends with threaded openings 8for the accommodation of the suspending rod 8.

The guide-knife structure 7 is made in the form of a frame having headportions 19, one or the other of which will be so disposed between therolls 3 and t and in proximity to the roll 2 as to guide the cane fromroll 3 to roll 4 and prevent it from getting be tween these rolls. Theguide-knife frame structure provides two pairs of wide bearing faces-21, the faces 20 being adapted in the arrangement shown in Figure 1 toengage the periphery of the roll 8 and the faces 21 being arranged toengage the pcriphery of the roll 4. To provide such extended bearingfaces for the guide-knife structure, requires considerable metal andthis insures the longevity of the device. The guide-knife structure isprovided at its respective ends with flanges or projections 22(preferably having curved or beveled inner faces) and these flanges orprojections enter between the flanges 5 of the'large roll 2 so as tofeed the cane in directions toward the center of the periphery of therolls and prevent the cane from escaping hey-"0nd one of said flanges 5to the gearing above or from droppingpast the other flange 5 to thebot-- tom of the mill.

With my improved double guide-knife structure, the same can be readilyreversed end for end when the active portions at one end of saidstructure become worn and by reversing the guide-knife structure axiallyas viewed in Figure 3, said structure can be adapted to permit the caneto be fed through the mill in a direction opposite to that indicated inFigure 1,it being understood that in such case the positions of therolls 3 and 4 will be changed so that the roll 3 will be disposed inclose proximity to the roll 2 and the roll 4 spaced from said roll 2 insubstantially the position which is represented in Figure 1 by the roll3.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is:

1. A reversible guide-knife structure for cane mills having two pairs ofroll engaging faces adapted for interchangeable use.

2. A reversible guide-knife structure for cane mills having oppositeheads providing, interchangeably, roll engaging portionsand meanswhereby said structure may be reversible in a cane mill.-

3. In a cane mill, the combination with framework and three rolls, oneof said rolls having flanges adjacent its ends, of a re versibleguide-knife structure having opposite heads providing, interchangeablyroll engaging portions, disposed between two of said rolls and havingflanges entering be tween the flanges of the other roll, and means foradjustably supporting said guide-knife structure.

4. In a cane mill, the combination with framework and three rolls, of areversible guide-knife structure having opposite heads providing,interchangeably, roll engaging portions disposed between two of saidrolls, means for adjustably suspending said guidelrnife structure fromthe framework, and means for adjustingsaid guide-knife structurerelatively to the roll orrolls with which it cooperates.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
